For each ticket I create I select a Client ID, eg Client_A
I also have a different ID that matches to this client i.e Client_A = Client_1, that I need to populate on this ticket in the field CustomerName.
Is there a way to define this lookup within JIRA, eg Client_A = Client_1, Client_B = Client_2, etc
And also do the lookup to populate this secondary field eg CustomerName.
